Instructions

Preheat your oven to 350°F (175°C). Grease or line a 9×13-inch baking pan with parchment paper.
In a large mixing bowl, combine the yellow cake mix, melted butter, vanilla extract, and eggs. Mix until a thick batter forms.
Fold in the chocolate chips until evenly distributed.
Press the batter evenly into the prepared baking pan using a spatula or your hands.
Sprinkle the Reese’s Pieces evenly over the top and press them gently into the surface.
Bake for 20–25 minutes, or until the edges are golden brown and the center is set.
Remove from the oven and allow the bars to cool completely in the pan.
Once cooled, slice into squares or rectangles and serve.

Use parchment paper for easy removal and cleaner slicing.
Check at the 20-minute mark to avoid overbaking.
